A jigsaw power tool is a jigsaw made up of an electric motor and a reciprocating saw blade. A jigsaw with a bevel function on the sole plate allows cutting angles of typically up to 45 degrees relative to the normal vertical stroke for cutting miter joints. Control is an issue with jigsaws. The blades are small, weak and entirely unsupported at the lower end. Good cut control requires the presence of blade rollers, which keep the blade aligned just above the sole plate. Heavy cast sole plate saws are somewhat better than pressed steel for sawing line control too. To guide a jigsaw on curved cut, it must be steered (turned) and not forced to move sideways. The usage of sharp blades is important also to get high quality cuts.
